Benjen travels south from the Wall to join in the feast welcoming King Robert Baratheon to Winterfell. He brings news about ill omens from beyond the Wall. Benjen tells Eddard that the young deserter he executed was a good and loyal man, a true ranger who would not desert his post lightly. He invites his nephew Jon Snow to join the Night's Watch; Jon agrees despite Benjen's warning that it is a hard life.[6] Eddard agrees to become the Hand of the King. A few days later, the royal party heads south. Benjen accompanies them to the Kingsroad and then escorts Jon and Tyrion Lannister north to Castle Black. Along the way they are joined by fresh recruits, including a rapist named Rast. Jon begins to realize that the Watch may not be the noble institution he thought it was.[7]

Upon arriving at Castle Black Jon begins his training. Benjen tells Jon that he is going north of the Wall on a ranging. Jon asks to go with him, but Benjen tells him that he is not ready and cautions that on the Wall a man only gets what he earns, not what his birth entitles him to. Benjen says farewell to his friend Yoren, a recruiter for the Watch. He also exchanges words with Tyrion, who is about to head south with Yoren. Benjen feels that Tyrion holds the Watch in disregard despite Tyrion's protests to the contrary.[8]

Benjen's horse returns to Castle Black, but there is no sign of Benjen himself.[11] Shortly afterwards, two of the rangers who accompanied Benjen, Othor and Jafer Flowers, are found dead in the forest beyond the Wall. They are brought back to Castle Black for Maester Aemon to study, but in the middle of the night they reanimate as wights. Both are killed again and their bodies are burned.[12] Lord Commander Jeor Mormont vows to take the Watch beyond the Wall in force to investigate what's going on and promises Jon that they will find Benjen alive or dead.[13]

In the books

In A Song of Ice and Fire, Benjen is the First Ranger of the Night's Watch, a position of high honor and achievement. It is rumored he took the black to escape from Winterfell because his home reminded him of his lost family (Rickard, Brandon, and Lyanna). He is a noted tracker and fighter. Benjen attends King Robert Baratheon's visit to Winterfell and Jon approaches him at the feast about joining the Night's Watch. Benjen tries to talk him out of making such a permanent decision at such a young age, but Jon's mind is made up. Benjen later tells Maester Luwin of Jon's decision, who in turn notifies Ned and Catelyn.

As with the TV series, Benjen goes on a mission to assess the situation in the Haunted Forest, but disappears and is never heard from again. The Great Ranging led by Night-Commander Mormont is organized partly in response to Benjen's disappearance.

According to the TV series official pronunciation guide developed for the cast and crew, "Benjen" is pronounced "BEN-jin", as opposed to "Ben-JENN" (the second syllable is short and not stressed).
